Combination 900 x 450 Indirect Copper Cylinder

Current package price:

This indirect combination cylinder is particularly suited to properties without loft space, e.g. flats, bungalows or bedsits. Designed to be used with a central heating system, the 900 x 450mm cylinder comprises a cold water cistern and a hot water tank in a single unit eliminating the need for a cold water storage tank and reducing installation costs.

How do I know if I need a vented or unvented copper storage cylinder? I have Economy 7 tariff.

The type of cylinder required depends on the your system setup. If the cylinder is fed by a cold water loft tank then you will require a vented cylinder. Whereas if you the cylinder is fed directly from the mains water in to the property then you will require an unvented cylinder.

are the dimensions with lagging if not what do you add for lagging, what are the pipe fitting sizes

The dimensions of the vented foam lagged cylinders on our website are for just the cylinder as this is how the manufacturer lists them. The lagging is 35mm on standard cylinders and 50mm on economy 7 cylinders.
So for standard cylinders you need to add 70mm to the width (35mm each side) and for the economy 7 cylinders you need to add 100mm to the width (50mm each side).
The immersion heater connection is 2.1/4" and the other pipe connections are generally 1" but on some of the larger size cylinders the connections are 1.1/4"
